‘Eight’ Final Boss Fight Details
| Aspect | Details |
|---|---|
| Arena | Terra Dome core chamber with shifting platforms, zero-gravity sections, and explosive debris. |
| Phases | 3 main phases triggered at 100%, 60%, and 25% health. |
| Weaknesses | Rear cooling vents, shield generators; hack-dependent. |
| Key Mechanic | Diana’s Holographic EMP + Hugh’s Charged Shotgun for posture breaks. |
| Difficulty Spike | Lunatic mode adds unblockable AOE bursts every 30 seconds. |
Preparing your loadout before facing Eight
Equip Hugh with the Heavy Railgun for armor penetration, Grip Gun for crowd control, and Stasis Net to immobilize adds. Upgrade Thrusters to level 5 for better evasion in zero-G, and max Mod Slots for Pocket Refinery (Lunafilament boost) and Tactical Scanner (reveals vents). Diana needs Hacking Damage Up modules to maximize node traversal on Eight’s complex firewall—aim for 8+ blue nodes per hack to triple vulnerability duration. Stock 4+ Refined Healing Injectors and full synergy gauge via pre-fight enemy clears. Farm Lunafilament from Terra Dome side rooms for these essentials.

- Laser Sweep: Eight charges a wide horizontal beam; telegraph is a 2-second red glow on vents. Counter by dashing perpendicular or grappling to upper platforms.
- Homing Missile Volley: 8-12 tracking projectiles from shoulder launchers. Intercept with Shockwave Gun bursts or hide behind debris pillars—never stand still.
- Lunge Combo: Three rapid dashes ending in ground slam AOE. Evade the first two to expose rear vents briefly; perfect parry the third (yellow flash on claw) for a stun window.
- Adds Summon: Deploys drones and Executor bots at 75% health. Use Grip Gun to chain two with one shot, then hack for group explosion.
- Overheat Burst (Phase 3): Steam vents signal a 360-degree flame ring. Grapple to ceiling debris and drop for a Charged Shotgun posture break.

Maintain constant motion—Eight’s scanners lock on stationary targets for instant orbital strikes.
How to survive phase 1 (100-60% health)

Step 3
Unload Railgun into exposed ports while dodging missile volleys—intercept 50% with Shockwave.
Step 4
When Diana signals “Flaw detected,” switch to Shotgun for posture break; repeat cycle twice.
Step 5
Clear summoned drones with Stasis Net chains before they overwhelm.
Phase ends when Eight overheats, slamming the arena floor and ejecting you to a zero-G segment—grapple tethers to stay oriented.
How to dominate phase 2 (60-25% health)
Arena shifts: platforms rotate, gravity fluctuates, adding disorientation.
Step 1
Hack during rotation pauses; Eight’s firewall thickens—hit 10 blue nodes for Overdrive trigger.

Step 2
Use zero-G to hover above laser sweeps, raining Armor-Piercing Rounds downward.
Step 3
Counter enhanced lunge (now five dashes) with parry on the fifth; exposes joints for 15-second crit window.
Step 4
Manage adds by hacking Executors to turn on drones—frees Hugh for boss focus.
Step 5
At 40% health, brace for AOE vacuum pull: tether to pillars and fire into maw during inhale cue.

Synergy gauge must stay above 70%—pre-hack adds to refill it passively.
How to clinch victory in phase 3 (under 25% health)
Eight enters berserk: speed doubles, new unblockable plasma orbs spawn.
Step 1
Diana auto-triggers Overdrive—damage triples, but i-frames drop; prioritize vents.
Step 2
Dodge orb clusters by thruster-jumping through gaps; destroy spawners with grenades.

Step 3
Chain hacks during brief stuns from perfect parries—unload everything into core.
Step 4
Final QTE at 5% health: mash hack inputs as Diana breaches Eight’s AI core.
Step 5
Execute cinematic finisher: Hugh’s melee strike synchronized with Diana’s shutdown pulse.
No-death run tip: Abuse grapple for untouchable positioning; Lunatic adds red “instant-kill” beams—audio cue is high-pitched whine.
